Here are a few options worth trying.
1.) Glycine — take it at night before bed. Minimum of 3grams, though 6-9 grams is also fine.
Should that not be enough...
2.) Magnesium glycinate — roughly 1,000 mgs before bed at night.
Should that not be enough...
3.) Give this 3-part stack a shot: Ashwagandha (the ksm66 version, 600mg), L theanine (200mg), and melatonin (5mg). Take 1 pill of each at night before bed.
NOW is the brand I use. Any brand you prefer is fine.

This sight (no affiliate code lol) is the one I normally go with. It carries a massive range of supplements and the prices tend to be the lowest.
Hope this helps.
